Registering and managing your devices for Duo Mobile multi-factor authentication

You can register your mobile phone, home phone, office phone, or even your tablet for Multi-factor Authentication. The only caveat is that only one person can register a shared phone number, such as an office phone shared by two or more employees or a home phone used by two employees. You must use a computer to register and have your phone available to complete the registration process.
